QgsPythonRunner(QgsPythonRunner)

Utility class for running Python commands from various parts of QGIS. There is no direct Python support in the core library, so it is expected that application with Python support creates a subclass that implements pure virtual function(s) during the initialization. The static methods will then work as expected.

isValid() → bool

Returns true if the runner has an instance (and thus is able to run commands) *

run(command: str, messageOnError: str = '') → bool

Execute a Python statement

runCommand(self, command: str, messageOnError: str = '') → bool
setInstance(runner: QgsPythonRunner)
